Frost

Lauren Frost has a choice to make: die, or save a foreign world to win her life back.

Eighteen-year-old Lauren Frost's life is split between two families and two continents. After spending the Christmas holiday in England with her mother, she comes home to a nightmare. Her Forty-two-year-old father has married his girlfriend, who is twenty-one and enjoys making Lauren miserable. So, Lauren flies back to England, considering leaving Florida and her father behind for good, until her mother reminds her that she'd be leaving her friends behind in the middle of her senior year. Plagued by indecision, Lauren goes for a walk that brings her life to a stand-still. However, the Messengers step in as she's dying and give her a choice. She can give up and die, or fight for a chance to reclaim her former life. The second option comes with a catch, though. She has to save a foreign world to win her life back.
